intensity for a maximum of 60 seconds
or until the driver’s and the front pas-
senger’s seat belt are fastened.
If you and/or your passenger release
the seat belt during driving, the seat
belt telltale < starts flashing and a
warning chime sounds as described be-
fore.
If the driver’s or the front passenger’s
seat belt remains unfastened after
60 seconds, the warning chime stops
sounding, the seat belt telltale<
stops flashing but continues to be illu-
minated.
After a vehicle standstill, the warning
chime is reactivated and the seat belt
telltale < is flashing again if the ve-
hicle speed once exceeds 15 mph
(25 km/h).
The seat belt telltale< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a door is opened.For more information, see “Practical hints”
(
page 385).
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts are equipped with emergen-
cy tensioning devices and belt force
limiters.
The ETD is designed to activate in the
following cases:

in frontal or rear-end impacts
exceeding the system deployment
threshold

if the restraint systems are operational
and functioning correctly,
see1indicator lamp (
page 64)When activated, emergency tensioning
devices remove slack from the belts. Belt
force limiters reduce the force exerted by
the seat belts on occupants during a crash.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
iThe ETDs for the front seats will only acti-
vate if the front seat belts are fastened (latch
plate properly inserted into buckle).
The ETDs for the rear seats will activate with or
without the respective seat belts fastened.
Warning!G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at any
authorized Mercedes-Benz Center.

Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.
Make sure the infant or child is proper-
ly secured at all times while the vehicle
is in motion.
Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual
manner.
Warning!G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could

injure themselves on parts of the vehicle

be seriously or fatally injured through
excessive exposure to extreme heat or
cold
If children open a door, they could

injure other persons

get out of the car and injure themselves
or be injured by oncoming traffic
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned on these
parts.
Do not carry heavy or hard objects in the
passenger compartment or trunk unless
they are firmly secured in place. For more in-
formation, see “Loading” (
page 275), and
see “Useful features” (
page 285) in the
“Controls in detail” chapter.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of

strong braking maneuvers

sudden changes of direction

an accidentWarning!G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.

84 Safety and Security
Occupant safety
The use of infant or child restraints is
required by law in all 50 states, the District
of Columbia, the U.S. territories, and all
Canadian provinces.
Infants and small children should be seat-
ed in an appropriate infant or child
restraint system properly secured in accor-
dance with the manufacturer's instruc-
tions for the child restraint, that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian Mo-
tor Vehicle Safety Standards 213 and
210.2.
A statement by the child restraint manu-
facturer of compliance with these stan-
dards can be found on the instruction label
on the restraint and in the instruction
manual provided with the restraint.When using any infant, or toddler restraint,
or booster seat, be sure to carefully read
and follow all manufacturer’s instructions
for installation and use.
Please read and observe warning labels
affixed to the inside of the vehicle and to
infant or child restraints.

chor fittings for tether anchorages (
page 86).
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint recom-
mended for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, or:
CLK coupe: the seat belt and top tether
strap, or lower anchors and top tether
strap,
CLK cabriolet: the seat belt and lower
anchors,
fully in accordance with the child seat
manufacturer’s instructions.
Occupants, especially children, should nev-
er place their bodies or lean their heads in
the area of the door or the rear side trim
panel where the front side impact air bag
(CLK cabriolet: head-thorax air bag) and/or
the rear side impact air bag* inflates. This
could result in serious injuries or death
should the air bag be triggered. Always sit as
upright as possible, properly use the seat
belts and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:

85 Safety and Security
Occupant safety

Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front air bag in your vehicle
when the OCS senses the weight of a
typical 12-month-old child or less along
with the weight of a standard
appropriate child restraint on the front
passenger seat.

A child in a rear-facing child restraint on
the front passenger seat will be
seriously injured or even killed if the
front passenger front air bag inflates in
a collision which could occur under
some circumstances, even with the air
bag technology installed in your vehicle.
The only means to completely eliminate
this risk is to never place a child in a
rear-facing child restraint in the front
seat. We therefore strongly recommend
that you always place a child in a
rear-facing child restraint in the back
seat.

If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to
do so, make sure the 56 indica-
tor lamp is illuminated, indicating that
the front passenger front air bag is deac-
tivated. Should the 56 indicator
lamp not illuminate or go out while the
restraint is installed, please check in-
stallation. Periodically check the
56 indicator lamp while driving
to make sure the 56indicator
lamp is illuminated. If the 56
indicator lamp goes out or remains out,
do not transport a child on the front pas-
senger seat until the system has been
repaired. A child in a rear-facing child re-
straint on the front passenger seat will
be seriously injured or even killed if the
front passenger front air bag inflates.

If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and
secure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions.
For children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activated
(
page 73).
Warning!G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children over 41 lbs until they reach a
height where a lap/shoulder belt fits
properly without a booster.

til it engages.
Check the rear seat backrest to be
locked in its upright position
(
page 282).
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an
accident and/or serious personal injury.
iYour CLK cabriolet does not have and is not
required to have anchorage rings for a child
seat’s top tether strap in the rear seating posi-
tions. Child seats can be used with the seat belt,
or lower anchor system and seat belt, fully in ac-
cordance with the child seat manufacturer’s in-
structions.
iFor safety, make sure the hook2 has at-
tached to the anchorage ring1 beyond the
safety catch, as illustrated.

tighten the top tether strap according to
the child restraint manufacturer’s instruc-
tions.
Child seat anchors – LATCH-type
The CLK coupe and cabriolet are equipped
with two LATCH- (L
ower Anchors and Teth-
ers for CH
ildren) type anchors (at each of
the rear seats) for the installation of a
LATCH-type child seat with matching
mounting fittings.LATCH-type anchors
The LATCH-type anchors are located be-
tween the seat cushion and the backrest.

In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts
properly as entire body parts or portions of
them may protrude from the passenger
compartment.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
